This Teen's Memory Resets Every 2 Hours

When this 16-year-old wakes up every day she believes it's June 11, 2019. For her, every day of the year is the same day.

It might sound a lot like the plot of the Bill Murray movie "Groundhog Day," But the rare form of amnesia that Riley Horner has is much more serious.

June 11 was a special day for Riley — she was attending a dance in her Illinois hometown. But the fun quickly turned to fear when a boy fell on her while crowdsurfing. She ended up hitting her head and being rushed to the hospital. She suffered several seizures in the hours after the incident.

"My last memory is me at the dance," Riley told Inside Edition.

Now, Riley's memory resets every two hours, making simple things like driving a nightmare. And Riley, who was a straight-A student who dreamed of becoming a doctor, can't even remember what she's learning in class.

Aside from memory loss, the teen also suffers migraines and light sensitivity. The injury also affected her speech and hearing.

"I do not wish this on anybody. This is horrible. This is torture," said mom Sarah Horner.

While her doctor determined that she suffered a concussion more severe than previously thought, her prognosis is good. Still, treatment will take time.

"I'm tired of June 11," Riley said.

The family has set up a GoFundMe to help with Riley's medical costs in getting her memory back.
